hi, I think this is related to fonts that are failing to load in 31.1 but I am unable to reproduce myself. The "Arial Black" font in your screenshot doesn't load for me on 31.1 but also doesn't cause a crash like this and we haven't had any other reports that I have seen so I think there might be another factor here. I'd like if you could fully uninstall your AVG antivirus and see if you're still having freezes like this.
